The extension section is provided with a cleaning fluid ejection port adapted to eject soapy water or the like for removing dirt and/or bacteria adhered to a user&#39;s hands. In this construction, the extension section continuously formed at a section of the overflow edge section of the bowl section functions as a conventional function case and as result, the number of parts and the number of execution man-hours can be reduced. Since a clearance or gap as seen in the prior art is not produced, cleaning efficiency can be improved. A cleaning fluid is filled in a tank, and a cleaning fluid refilling port for refilling the cleaning fluid from the tank is provided on the inner surface of a water receiving section. The cleaning fluid within the tank is supplied to the cleaning fluid ejection port by a pump. In this manner, it is possible to easily refill the cleaning fluid without dirtying the function case or a counter.

BACKGROUND OF THE INVENTION

[0001] 1. Field of the Invention

[0002] The present invention relates to a wash-hand basin or a hand-washing device which is installed in an ordinary household, a public lavatory or a washroom and the like.

[0003] 2. Description of the Prior Art

[0004] A conventional wash-hand basin or hand-washing device of this kind is, for example, disclosed in Japanese Unexamined Patent Publication No. Hei 1-236023 (1989).

[0005] As shown in FIG. 26, a hand-washing device main body 100 is provided with a bowl section 200, and a function case 300 is mounted on a counter 400 which is provided along an edge of the bowl section 200. A soapy water ejection nozzle 500, a hand-washing water ejection nozzle 600 and a warm air blowing nozzle 700 are provided on a front surface of the function case 300 to respectively communicate and connect with a soapy water supply device, a hand-washing water supply device and a warm air generating device which are stored in the hand-washing device main body 100.

[0006] A refilling port 800 for refilling soapy water is provided on the upper section of the function case 300, and a cover 900 is mounted on the upper end of the function case 300 to cover the refilling port 800. Reference numerals 500 a, 600 a and 700 a are hand detecting sensors provided near the soapy water ejection nozzle 500, the hand-washing water ejection nozzle 600 and the warm-air blowing nozzle 700 to detect a user's hands stretched out thereto and transmit the detection signal to a control section.

[0007] In this manner, a user can wash his hands first and dry them without shifting his position.

[0008] However, in the above-mentioned conventional structure, when soapy water is refilled, the cover 900 must be removed from the function case 300. It is therefore troublesome to carry out the refilling operation. Further, there is a problem that when refilled, the soapy water will spill out to make the function case 300 and the counter 400 dirty. There is another problem that the spilt soapy water will adhere to hand detecting sensors 500 a, 600 a and 700 a to fail to detect the user's hands stretched out thereto and as a result, the soapy water is not ejected from the soapy water ejection nozzle 500 or water is not ejected from the hand-washing water ejection nozzle 600.

[0009] Further, in such a conventional structure, since a wash-hand basin main body is separate from a function case, there is a problem that the number of parts and the number of execution man-hours increase to let the execution of works take time.

[0010] Still further, there is a problem that the cleaning efficiency is not good because a clearance or gap is produced between the wash-hand basin main body and the function case.

DISCLOSURE OF THE INVENTION

[0011] In the prior art, there is caused a clearance or gap between a wash-hand basin main body and a function case. Accordingly, cleaning is not only efficient, but also assembling works of the wash-hand basin main body with the function case can not be easily performed and a cleaning fluid such as soapy water can not be easily refilled. Inventors have now formed a first group of invention by extending upward a section of an overflow edge section of a bowl section of a wash-hand basin main body to provide an extension section and providing the extension section with a cleaning fluid ejection port for ejecting soapy water or the like. Inventors have also formed a second group of invention by filling a cleaning fluid into a tank, forming a cleaning fluid refilling port for refilling the cleaning fluid from the tank on an inner surface of a water receiving section, and supplying the cleaning fluid ejection port with the cleaning fluid within the tank by a pump.

[0012] As the first group of invention, it is desirable that a wash-hand basin main body, an extension section formed by extending upward a section of an overflow edge section of a bowl section of the wash-hand basin main body, and a cleaning fluid ejection port provided on the extension section to eject soapy water or the like for removing dirt, bacteria or the like adhered to a user's hands be provided.

[0013] Since the extension section continuously formed on the section of the overflow edge section of the bowl section functions as a conventional function case, it is possible to reduce the number of parts and the number of execution man-hours and easily carry out the execution works. Since there is not produced a clearance or gap as seen in the prior art, cleaning efficiency can be can be improved.

[0014] If the cleaning fluid ejection port is designed to eject soapy water or the like toward the bottom surface side of the bowl section, the ejected soapy water or the like can be surely received by the bowl section. Since scattering of the soapy water or the like onto the peripheral members such as a counter of a wash-hand basin can be prevented, it is possible to keep cleanliness.

[0015] If a rear section of the overflow edge section of the bowl section is extended upward to form the extension section, the cleaning fluid ejection port can be situated at a position facing the user. In this case, a hand-washing motion using the cleaning fluid can be easily carried out and the usability of the wash-hand basin improves.

[0016] It is also desirable that the wash-hand basin main body, the extension section formed by extending upward a section of the overflow edge section of the bowl section of the wash-hand basin main body, and a water ejection port provided on the extension section for ejecting hot or cold water be provided.

[0017] Since the extension section continuously formed on a section of the overflow edge section of the bowl section functions as a conventional function case, it is not only possible to reduce the number of parts and the number of execution man-hours, but also to easily carry out the execution works. Further, since there is not produced a conventional clearance or gap, cleaning efficiency can be improved.

[0018] In the case where a user washes his face and hands with hot or cold water ejected by the water ejection port, scattering of the hot or cold water is received at the extension section. Since scattering of the hot or cold water onto the peripheral member such as a counter of the wash-hand basin is prevented, cleanliness can be maintained.

[0019] If the water ejection port is provided to eject hot or cold water toward a bottom surface of the bowl section, the ejected hot or cold water can be received more certainly at the bowl section. In this manner, scattering of the soapy water or the like onto the peripheral member such as a counter of the wash-hand basin can be prevented and as a result, cleanliness can be maintained.

[0020] If a rear section of the overflow edge section of the bowl section is extended upward to form the extension section, the water ejection port is situated at a position facing the user. As a result, the hand-washing motion with hot or cold water can be easily performed and usability of the wash-hand basin improves.

[0021] It is also desirable that the wash-hand basin main body, the extension section formed by extending upward a section of the overflow edge section of the bowl section of the wash-hand basin main body, and a gas blowing port provided on the extension section for blowing gas for blowing off the drops of water or the like adhered to the user's hands be provided.

[0022] Since the extension section continuously formed on a section of the overflow edge section of the bowl section functions as a conventional function case, it is not only possible to reduce the number of parts and the number of execution man-hours, but also to easily perform the execution works. Since there is not produced a clearance or gap as seen in the prior art, clean efficiency can be improved.

[0023] If the gas blowing port for blowing gas for blowing off the drops of water or the like adhered to the user's hands is provided on the extension section, the user can dry his hands without shifting his position and usability of the wash-hand basin improves. Since the counter of the wash-hand basin, a floor or the like is not dirtied with the drops of water or the like adhered to the user's hands, clean space can be maintained.

[0024] If the bowl section other than the extension section is provided with a gas blowing port for blowing gas for blowing off the drops of water or the like adhered to the user's hands, the user can dry his hands without shifting his position and usability of the wash-hand basin improves. Further, since the counter of the wash-hand basin, the floor or the like is not dirtied with the drops of water or the like adhered to the hands, clean space can be maintained. Still further, since the user stretches out his hands inside the bowl section for drying, there is little possibility that the counter of the wash-hand basin or the like is dirtied with the drops of water blown off from the hands. It is also possible to further maintain the cleanliness.

[0025] When the gas blowing port is provided at the front side of the bowl section, the gas blown from the gas blowing port is blown off in the direction away from the user. Accordingly, there is little possibility that the gas after striking the hands strikes again the user to disturb his hairstyle or the drops of water or the like blown off by the gas splash on the user. It is therefore possible to obtain comfortable feeling of use.

[0026] If the gas blowing port is provided with a blowing axis for allowing the gas to blow downward or in a substantially horizontal direction, the blowing direction of gas from the gas blowing port is orientated to the inside of the bowl section. Accordingly, there is little possibility that the counter of the wash-hand basin or the like is dirtied with the drops of water or the like blown off from the hands, and as a result, cleanliness can be further maintained.

[0027] If the gas blowing port is provided to allow the blowing axis to face the extension section and the blowing axis is situated at the lower side than the top of the extension section, the drops of water or the like blown off from the hands can be received more certainly by the extension section or the bowl section. As a result, there is little possibility that the counter of the wash-hand basin or the like is dirtied, and cleanliness can be further maintained.

[0028] When a hollow chamber is provided at the front side of the bowl section and it is used as an air duct for supplying the gas blowing port with the gas, the blowing pressure of gas can be uniformalized within the chamber to allow the gas with the uniform velocity of wind to blow from the gas blowing port. In this case, the chamber can be integrally formed with the bowl section and the number of parts such as a duct for ventilation and a packing member can be reduced. As a result, a reduction in costs can also be attained.

[0029] If the wash-hand basin main body is made of pottery or ceramics, it is not only possible to easily clean dirt such as soapy water and/or drops of water adhered to the bowl section and/or the extension section, but also the air duct can be integrally formed with the bowl section without difficulty.

[0030] If there is provided a hand detecting means for detecting the hands stretch out in front of the cleaning fluid ejection port, the water ejection port or the gas blowing port and the hand detecting means is provided near the cleaning fluid ejection port, the water ejection port or the gas blowing port, it is possible to automatically let eject the cleaning fluid such as soapy water and hot or cold water or let the gas blow without touching an appliance or the like. Accordingly, usability of the wash-hand basin not only improves, but also cleanliness can be maintained.

[0031] If the hand detecting means is integrally formed with the cleaning fluid ejection port, the water ejection port or the gas blowing port, it is possible to reduce the number of parts used and attain the reduction in costs.

[0032] If the extension section is formed to tilt in the front direction of the bowl section, it is possible to make the construction of the wash-hand basin compact by controlling the extent of the upward projection. Even though the cleaning fluid and the drops of water or the like adhere to the extension section, it is designed to let them flow easily and as a result, cleaning can also be easily carried out. Further, when the gas blowing port is provided at the front side of the bowl section, it is possible to deter the drops of water or the like blown off from the hands by the gas blown off from the gas blowing port from scattering onto the wall surface facing the user, the counter or the like.

[0033] If the extension section is provided with an opening section for mounting the cleaning fluid ejection port, the water ejection port or the gas blowing port, and the cleaning fluid ejection port, the water ejection port or the gas flowing port is mounted on the opening section from the side of the bowl section via a fitting member, it is possible to carry out mounting or dismounting operation from the front side when mounting or maintenance of the cleaning fluid ejection port, the water ejection port or the gas flowing port is performed. As a result, workability not only improves, but also working hours can be reduced.

[0034] It is also desirable that a wash-hand basin main body, an extension section formed by extending upward a section of an overflow edge section of a bowl section of the wash-hand basin main body, a cleaning fluid ejection port for ejecting soapy water or the like adapted to remove dirt and/or bacteria adhered to a user's hands onto the extension section, and a cleaning fluid supply device for supplying the cleaning fluid ejection port with soapy water or the like be provided.

[0035] Since the extension section continuously formed on a section of the overflow edge section of the bowl section functions as a conventional function case, it is not only possible to reduce the number of parts and the number of execution man-hours, but also to easily perform the execution works. Since there is not produced a clearance or gap as seen in the prior art, it is possible to provide a hand-washing device which can improve the cleaning efficiency.

[0036] It is also desirable that the wash-hand basin main body, the extension section formed by extending upward a section of the overflow edge section of the bowl section of the wash-hand basin main body, the water ejection port for ejecting hot or cold water onto the extension section, and a hot and cold water supply device for supplying the water ejection port with the hot and cold water be provided.

[0037] The extension section continuously formed on a section of the overflow edge section of the bowl section functions as a conventional function case. Accordingly, it is not only possible to reduce the number of parts and the number of execution man-hours, but also to easily carry out the execution works. Since there is not produced a clearance or gap as seen in the prior art, it is possible to provide a hand-washing device which can improve the cleaning efficiency.

[0038] When the user washes his face and hands with hot or cold water ejected from the water ejection port, the extension section is designed to receive scattering of the hot or cold water. Accordingly, it is possible to prevent the hot or cold water from scattering onto the peripheral member such as the counter of the wash-hand basin, and as a result, cleanliness can be maintained.

[0039] It is also desirable that the wash-hand basin main body, the extension section formed by extending upward a section of the overflow edge section of the bowl section of the wash-hand basin main body, and the gas blowing port for blowing the gas for blowing off the drops of water or the like adhered to the user's hands onto the extension section be provided.

[0040] Since the extension section continuously formed on a section of the overflow edge section of the bowl section functions as a conventional function case, it is possible to reduce the number of parts and the number of execution man-hours and easily carry out the execution works. Since there is not produced a clearance or gap as seen in the prior art, it is possible to provide a hand-washing device which can improve the cleaning efficiency.

[0041] If a gas supply device for supplying the gas blowing port with gas is provided, the user can dry his hands without shifting his position and as a result, usability of the hand-washing device improves. Since the counter of the wash-hand basin, the floor or the like is not dirtied with the drops of water or the like adhered to the user's hands, clean space can be maintained.

[0042] If the bowl section other than the extension section is provided with a gas blowing port for blowing the gas for blowing off the drops of water or the like adhered to the user's hands and a gas supply device for supplying the gas blowing port with gas is provided, the user can dry his hands without shifting his position and as a result, usability of the hand-washing device improves. Since the counter of the wash-hand basin, the floor or the like is not dirtied with the drops of water or the like adhered to the user's hands, clean space can be maintained. Since the hands can be inserted within the bowl section for drying, there is little possibility that the counter of the wash-hand basin or the like is not dirtied with the drops of water or the like blown off from the hands, and as a result, cleanliness can be further maintained.

[0043] If the gas supply device is constructed to supply the gas blowing port with high-pressure gas, the wet hands can be dried in a short time.

[0044] A hand detecting means for detecting the user's hands stretched out in front of the cleaning fluid ejection port, the water ejection port or the gas blowing port, a control section for controlling drive of the cleaning fluid supply device, the hot and cold water supply device or the gas supply device based on the detection signal from the hand detecting means, and an operating switch are provided, wherein when an actuating signal by the operating switch is inputted, the control section controls to invalidate the detection signal by the hand detecting means for a certain period of time. In the case where the wash-hand basin is cleaned, the hand detecting means senses the user's hands to actuate the cleaning fluid supply device, the hot and cold water supply device or the gas supply device. In this manner, it is possible to prevent the cleaning fluid and/or the hot and cold water from scattering to dirty a counter, a wall surface or the like. It is also possible to prevent the cleaning fluid, hot and cold water or electricity from being consumed uselessly.

[0045] The control of invalidation of the hand detecting signal by the operating switch for a certain period of time is removed if there is re-input by the operating switch within the certain period of time. Accordingly, even though cleaning of the wash-hand basin is completed within the predetermined period of time, the control of invalidation for the predetermined period of time is continued and the wash-hand basin can still be used until removed.

[0046] A counter for mounting the wash-hand basin main body is provided, the extension section is provided with a hollow section, and the rear wall of the extension section is formed to extend upward from the upper or lower surface of the counter, wherein a connecting member for communicating and connecting the cleaning fluid ejection port, the water ejection port or the gas blowing port with the cleaning fluid supply device, the hot and cold water supply device or the gas supply device is connected via the hollow section to the cleaning fluid ejection port, the water ejection port or the gas blowing port. In such a construction, since the connecting member is hidden behind the hollow section formed in the extension section, the external appearance can be improved.

[0047] A second group of invention is provided to comprise a water ejection port for ejecting hot or cold water, a cleaning fluid ejection port for ejecting soapy water or the like for removing dirt, bacteria or the like adhered to a user's hands, a cleaning fluid supply means for supplying the cleaning fluid ejection port with a cleaning fluid, a water receiving section for receiving water from the water ejection port and the clean fluid from the cleaning fluid ejection port, and a drain port provided at a lower section of the water receiving section, wherein the cleaning fluid supply means comprises a tank for filling the cleaning fluid therein, a cleaning fluid refilling port for refilling the cleaning fluid into the tank, a supply route for communicating the tank with the cleaning fluid refilling port, and a pump for supplying the cleaning fluid ejection port with the cleaning fluid within the tank via a cleaning fluid supply route, wherein the cleaning fluid refilling port is provided inside the water receiving section.

[0048] Since refilling of the cleaning fluid such as soapy water can be performed within the water receiving section, even in the case where the cleaning fluid is spilt, it is possible to easily clean the cleaning fluid and discharge it from the drain port. For example, even though the water ejection port and/or the cleaning fluid ejection port are provided in a function case as before, it is possible to provide a highly reliable hand-washing device without polluting the function case or the counter.

[0049] If the water receiving section is formed in a substantially oval shape which is wide in the lateral direction and the cleaning fluid refilling port is provided on either side of the right or the left of the water receiving section, refilling of the cleaning fluid can be easily performed in an easy position even in the case of a comparatively large cleaning fluid refilling container.

[0050] If the cleaning fluid refilling port is situated at a position of about ⅓ depth from the upper end of the depth of the water receiving section from the upper end to the bottom surface, it is possible to easily situate an inlet of the cleaning fluid refilling container relative to the cleaning fluid refilling port when the cleaning fluid is refilled. Accordingly, refilling works can be easily performed without spilling the cleaning fluid.

[0051] The extension section is formed by extending upward a rear section of the water receiving section and provided with the water ejection port and the cleaning fluid ejection port, wherein the front section of the water receiving section is provided with a gas blowing port for blowing off the drops of water or the like adhered to a user's the hands. In this manner, the water ejection port, the cleaning fluid ejection port and the gas blowing port are situated at a position away from the cleaning fluid refilling port. Accordingly, when the cleaning fluid is refilled, the position does not have a bad influence on the function area of the water ejection port, the cleaning fluid ejection port and the gas blowing port. Further, since the blown drops of water or the like are received at the extension section, it is possible to prevent the drops of water or the like from polluting the counter or the like.

[0052] If a lid is provided to cover the cleaning fluid refilling port and detachably mounted on the cleaning fluid refilling port by a detachable means, it is possible to prevent garbage or the like from entering the cleaning fluid refilling port.

[0053] The detachable means comprises a concave area formed on the inner periphery of the cleaning fluid refilling port or on the outer periphery of the lid, a convex area formed on the outer periphery of the lid or on the inner periphery of the cleaning fluid refilling port to be inserted into the concave area for engagement, a groove section formed on the inner surface of the cleaning fluid refilling port or on the outer surface of the lid to let the convex area pass from the concave area, and a spring inserted between the inner periphery of the cleaning fluid refilling port and the outer periphery of the lid to energize the lid in the direction away from the cleaning fluid refilling port when the lid is mounted on the cleaning fluid refilling port. In this manner, engagement of the concave area of the cleaning fluid refilling port with the convex area of the lid rotates the lid and the convex area of the lid passes from the groove section to let the lid rise by the energizing force of the spring. Accordingly, the lid can be easily dismounted from the cleaning fluid refilling port using a simple construction.

[0054] If the outside of the lid is provided with a grip for holding, the lid can be dismounted more easily.

[0055] The detachable means has a lid provided with an inner joint which joins with the inner periphery of the cleaning fluid refilling port and an outer joint which joins with the outer periphery of the cleaning fluid refilling port, wherein the inner joint and the outer joint are partially cut out to form a cutout section into which an energizing member with a pressure contact section energized onto the inner periphery of the cleaning fluid refilling port is situated. Since engagement of the cleaning fluid refilling port with the lid is disengaged by reducing the energizing member against the energizing force, mounting of the lid on or dismounting thereof from the cleaning fluid refilling port can be easily performed with a simple construction.

[0056] The detachable means has a lid made of an elastic body and formed in an arc shape in section so that the lid projects inside the water receiving section when mounted on the cleaning fluid refilling port, wherein the outer periphery of the lid is provided with an engaging section adapted to engage the cleaning fluid refilling port and the outer surface of the cleaning fluid refilling port is provided with a section to be engaged by the engaging section. When the central part thereof is pushed, the lid is bent backward in the arc shape to disengage the engagement with the cleaning fluid refilling port. In this manner, the lid can be easily dismounted from the cleaning fluid refilling port with a simple construction.

[0057] The detachable means has a magnetic substance provided on either of the outer periphery of the lid or the inner periphery of the cleaning fluid refilling port and has a non-magnetic substance adapted to attach to the magnetic substance provided on the other. In this manner, mounting the lid on or dismounting thereof from the cleaning fluid refilling port can be easily performed with a simple construction.

[0058] The magnetic substance and the non-magnetic substance are respectively provided at the symmetric position of the lid or the cleaning fluid refilling port, wherein the position of one is situated more inwardly than the other. By pushing part of the lid, the lid rises and can be easily dismounted.

[0059] If a grip is provided on the outside of the lid for holding, the lid can be dismounted more easily.

[0060] A connecting member is provided to connect the lid to the cleaning fluid refilling port. Even though the lid is dismounted from the cleaning fluid refilling port, the cleaning fluid refilling port and the lid are still connected together. It is therefore possible to prevent the loss of the lid.

[0061] The lid is provided to cover the cleaning fluid refilling port, wherein the lid can be mounted on or dismounted from the cleaning fluid refilling port by a connecting means. With this construction, it is not only possible to prevent garbage or the like from entering the cleaning fluid refilling port, but also to prevent the loss of the lid.

[0062] The connecting means is a hinge which can mount the lid on or dismount it from the cleaning fluid refilling. Opening and closing of the lid can be easily carried out with a simple construction.

[0063] If the hinge is constructed to let the lid open and close forward, opening and closing operation of the lid can be easily performed.

[0064] If the hinge is constructed to let the lid open and close inside the cleaning fluid refilling port, the lid does not hinder the refilling operation of the soapy water. Thus, the refilling operation can be easily performed.

[0065] The lid is provided at its lower section with a weight to be brought into a closing condition by its own weight, and the cleaning fluid refilling port is provided on the water receiving section so that when closed, the lid becomes vertical or tilts to situate its lower end outside the water receiving section. With this construction, opening and closing of the lid can be easily performed.

[0066] The lid is provided at its lower section with a weight to be brought into a closing condition by its own weight, and the cleaning fluid refilling port is provided on the water receiving section so that when closed, the lid is kept in a substantially vertical condition, wherein a magnetic substance is provided on either the lower section of the lid or the lower section of the cleaning fluid refilling port, while a non-magnetic substance adhered to the magnetic substance is provided on the other. In this manner, opening and closing of the lid can be easily performed and it is also possible to prevent the lid from opening unpreparedly.

[0067] The connecting means comprises a rotating shaft provided on the lid, a through-hole provided on the cleaning fluid refilling port to let the rotating shaft insert therein, and an anti-slip member provided on the tip of the rotating shaft to prevent the shaft from slipping out of the through-hole. In this manner, opening and closing operation of the lid can be easily performed with a simple construction.

[0068] There is also provided an engaging means for preventing the lid from opening unpreparedly. For example, even though the hand or the like touches the lid during action within the water receiving section, the lid does not simply open. Accordingly, usability of the hand-washing device not only improves, but also it is possible to prevent garbage or the like from entering the cleaning fluid refilling port.

[0069] The engaging means has a magnetic substance provided on either the lid or the cleaning fluid refilling port and a non-magnetic substance adapted to adhere to the magnetic substance provided on the other. The engaging means is also provided to form an engaging section or a section to be engaged on the cleaning fluid refilling port and to from a section to be engaged or an engaging section on the lid for engaging with the engaging section or the section to be engaged of the cleaning fluid refilling port. In this manner, it is possible with a simple construction to prevent the lid from opening unpreparedly.

[0070] If a strainer is provided to prevent dust or the like from entering the inside of the cleaning fluid refilling port, it is possible to prevent the dust or the like from entering the cleaning fluid refilling port when the cleaning fluid is refilled. Accordingly, it is possible to prevent a cleaning fluid supply route from being blocked by the dust or the like to stop discharging of the soapy water from the cleaning fluid ejection port. It is also possible to prevent damage of a pump or the like.

[0071] If the strainer is provided with a grip and a stopper for positioning the strainer is provided inside the cleaning fluid refilling port, it is possible to easily carry out cleaning of dust or the like adhered to the strainer.

[0072] There is provided a liquid level detecting means for detecting that the upper surface of the cleaning fluid within the cleaning fluid refilling port has reached a certain liquid level, and an information means for informing that the upper surface of the cleaning fluid has reached the certain liquid level based on the detection signal from the liquid level detecting means. In this manner, it is possible to easily grasp a filling condition of the cleaning fluid within the cleaning fluid refilling port when refilled and to prevent the cleaning fluid from overflowing therefrom.

[0073] A float rising by buoyancy when the cleaning fluid refilling port is substantially filled with the cleaning fluid is provided inside the cleaning fluid refilling port. With this construction, it is possible to easily grasp the filling condition of the cleaning fluid within the cleaning fluid refilling port by the motion of the float when refilled. It is also possible to prevent the cleaning fluid from overflowing with a simple construction.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0101] Preferred embodiments of a first group of invention according to the present invention will now be described with reference to the: accompanying drawings. FIG. 1 is a perspective view of the external appearance showing a first embodiment of a hand-washing device according to the present invention. FIG. 2 is a schematic cross-sectional view showing the first embodiment of the hand-washing device according to the present invention.

[0102] As shown in FIGS. 1 and 2, a hand-washing device A comprises a wash-hand basin 1, a cleaning fluid supply device 2 for supplying the wash-hand basin 1 with a cleaning fluid such as a disinfecting fluid and soapy water for removing dirt and/or bacteria adhered to a user's hands 22, and a hot and cold water supply device 3 for supplying hot or cold water.

[0103] The wash-hand basin 1 is composed of a wash-hand basin main body 11, an extension section 106 formed by extending upward a rear section of an overflow edge section 103 a of a bowl section 103 formed in a concave shape of the wash-hand basin main body 11, a cleaning fluid ejection port 13 provided on the extension section 106 to eject soapy water or the like, and a water ejection port 12 for ejecting hot or cold water.

[0104] The extension section 106 is provided to tilt toward the front of the bowl section 103 and formed with a hollow section 106 c. A cleaning fluid ejection port 13 and a water ejection port 12 are respectively secured via fixing members 13 b, 13 c, 12 b and 12 c to opening sections 106 b and 106 b formed on the front wall 106 a of the extension section 106 by securing means 13 d and 12 d such as a screw from the front side of the bowl section 103.

[0105] Hand detecting sensors 13 a and 12 a are also mounted on the fixing members 13 b and 12 b respectively.

[0106] The wash-hand basin main body 11 is made of pottery and provided with a drain port 105 at the central lowest position of the bowl section 103 to communicate with a drain pipe 15 disposed within a cabinet section 100 described below. The wash-hand basin main body 11 is kept in position by a method (e.g., a self-rimming method or a frame method) for engaging a rim section 104 of the wash-hand basin main body 11 and a rear wall 106 d of the extension section 106 with an opening section 102 formed at a substantially central section of a counter 10.

[0107] The counter 10 is, for example, made of an artificial marble in a flat plate shape and installed to cover the upper part of the cabinet section 100 provided thereunder. Disposed between the upper side of the counter 10 and the lower side of the rim section 104 and the rear wall 16 d of the extension section 106 is a sealing medium (not shown) to prevent water from entering the cabinet section 100.

[0108] The cabinet section 100 is formed in a hollow box shape of which the front side is provided with a decorative panel 101 and houses the cleaning fluid supply device 2 and the hot and cold water supply device 3 therein.

[0109] The cleaning fluid supply device 2 consists of a cleaning fluid storing tank 19 for storing a cleaning fluid therein and a cleaning fluid pressure pump 18 for supplying the cleaning fluid stored within the cleaning fluid storing tank 19 under pressure. The cleaning fluid supply device 2 is provided to communicate and connect via a cleaning fluid supply hose 17 with the cleaning fluid ejection port 13 within the hollow section 106 c of the extension section 106.

[0110] On the other hand, the hot and cold water supply device 3 consists of stop cocks 21 and 21 respectively connected to a hot water pipe 40 and a water pipe 41, a hot and cold water mixed cock 20 connected to the stop cocks 21 and 21 to generate a hot water of a suitable temperature, and a solenoid valve (not shown) connected to the hot and cold water mixed cock 20. The hot and cold water supply device 3 is provided to communicate and connect via a hot water supply hose 16 with the water ejection port 12 within the hollow section 106 c of the extension section 106.

[0111] Installation of the wash-hand basin main body 11 onto the counter 10 is not limited to the self-rimming method or the frame method, but as shown in FIG. 3, the wash-hand basin main body 11 can be installed by another method (i.e., an under-counter method) whereby a brim section 106 e continuously formed on the overflow edge section 103 a of the bowl section 103 and the rear wall 106 d of the extension section 106 is positioned to engage with the lower surface side of the counter 10.

[0112] The cleaning fluid supply device 2 and the hot and cold water supply device 3 are disposed within the cabinet section 100 so that they are not exposed, but only the lower section of the wash-hand basin main body 11 can be covered.

[0113] Namely, as shown in FIGS. 4 and 5, a casing 107 formed in a hollow box shape is firmly secured to a wall surface W using mounting screws 23. The wash-hand basin main body 11 is thus installed by a method (e.g., the self-rimming method or the frame method) whereby a rim section 104 of the wash-hand basin main body 11 and the rear wall 106 d of the extension section 106 are supported by engaging with an opening 108 formed on an opening section 108 provided on the substantially central section of the casing 107.

[0114] Provided on the bottom wall 107 a of the casing 107 are an opening 109 through which a drain pipe 15 and a cleaning fluid supply hose 17 pass and an opening 110 through which a hot water supply hose 16 passes.

[0115] A sealing medium (not shown) is provided between a counter section 107 b on the upper side of the casing 107 and a lower side of the rim section 104 and the rear wall 106 d of the extension 106 to prevent water form entering the casing 107.

[0116] Further, the bottom wall 107 a of the casing 107 can be constructed to open and close so that installation of the wash-hand basin main body 11 onto the counter section 107 b of the casing 107 is executed by the under-counter method in the same manner as the embodiment shown in FIG. 3.

[0117] Operation of the hand-washing device A as constructed above will be described hereunder.

[0118] When a user inserts his hands 22 into the bowl section 103 and stretches out them in front of a hand detecting sensor 13 a, a control section (not shown) controls to drive the cleaning fluid pressure pump 18 based on the detection signal from the hand detecting sensor 13 a to supply the cleaning fluid stored within the cleaning fluid storing tank 19 under pressure. In this manner, the cleaning fluid under pressure is ejected from the cleaning fluid ejection port 13 via the cleaning fluid supply hose 17 and the user carry out the motion to remove dirt and/or stains from his hands 22.

[0119] In this case, even though the ejected cleaning fluid strike the hands 22 and scatter, the cleaning fluid drop direct into the bowl section 103 or adhere to the front wall 106 a of the extension section 106 before dropping into the bowl section 106. Accordingly, there is little possibility of polluting the peripheral counter 10 and the like. Further, since the wash-hand basin main body 11 is made of pottery or ceramics, cleaning efficiency can be improved. Since the ejection motion of the cleaning fluid is automatically carried out by the hand detecting sensor 13 a, the user is not required to touch an appliance such as a lever for opening and closing operation and it is hygienic and good for the user's health. Further, since the extension section 106 serves as the conventional function case, it is possible not only to reduce the number of parts used and the number of execution man-hours, but also to easily carry out the execution works. Still further, since there is not produced a conventional clearance or gap, it is possible to improve the cleaning efficiency.

[0120] After removing dirt or stains from his hands 22 using the cleaning fluid, the user stretches out his hands 22 in front of the hand detecting sensor 12 a, the control section (not shown) controls to drive a solenoid valve based on the detection signal from the hand detecting sensor 12 a. As a result, the hot water is ejected from the water ejection port 12 via the hot water supply hose 16 and the user starts washing his hands.

[0121] In this case, even though the ejected hot water strike the user's hands 22 and scatter, the hot water drop direct into the bowl section 103 or adhere to the front wall 106 a of the extension section 106 before dropping into the bowl section 103. Accordingly, there is little possibility of polluting the peripheral counter 10 and the like and cleaning efficiency can be improved. Further, since the water ejecting motion can be automatically carried out by the hand detecting sensor 12 a, the user is not required to touch the appliance such as the opening/closing operation lever. It is therefore hygienic and good for the user's health.

[0122] The extension section 106 of the wash-hand basin main body 11 is provided behind the overflow edge section 103 a of the bowl section 103. However, it can also be provided on the right side or the left side of the overflow edge section 103 a of the bowl section 103, from the right side to the rear side, or from the left side to the rear side.

[0123] The wash-hand basin main body 11 is not made of the pottery or ceramics, but made of the member such as a stainless steel which is superior in the cleaning efficiency. The area from the bowl section 103 to the front wall 106 a of the extension section 106 can be continuously and integrally made of the pottery or ceramics, while the rear wall 106 d of the extension section 106 can be made of the member other than the pottery or ceramics.

[0124]FIG. 6 is a perspective view of the external appearance showing a second embodiment of a hand-washing device A according to the present invention and FIG. 7 is a schematic cross-sectional view showing the second embodiment of the hand-washing device A according to the present invention. The same construction as the first embodiment is indicated by the same reference numeral and the description for that will be omitted.

[0125] As shown in FIGS. 6 and 7, there is provided on a front wall surface of the bowl section 103 a gas blowing port 27 for blowing gas for blowing off the drops of water or the like attached to the user's hands. The gas blowing port 27 is arranged to blow the gas toward the lower side of the bowl section 103 and in the direction away from the user.

[0126] A chamber 28 formed in a hollow shape is integrally formed with the bowl section 103 on the reverse side of the wall surface of the bowl section 103 provided with the gas blowing port 27. An adapter 26 is connected to the chamber 28.

[0127] A gas supply device 24 consisting of an air blower and the like for supplying the gas blowing port 27 with high-pressure gas is provided within the cabinet 100. One end of an air duct 25 is connected to the gas supply device 24 and the other end is connected to the adapter 26.

[0128] Provided near the gas blowing port 27 is a hand detecting sensor 27 a for detecting the user's hands inserted into the bowl section 103 and driving the gas supply device 24.

[0129] Operation of the hand-washing device A constructed above will now be described.

[0130] A user inserts his hands 22 into the bowl section 103 and stretches out the hands 22 in front of the hand detecting sensor 13 a to allow the cleaning fluid to eject from the cleaning fluid ejection port 13. After removing dirt or stains from the hands 22, the user stretches out the hands 22 in front of the hand detecting sensor 12 a to allow the hot water to eject from the water ejection port 12 and washes the hands 22. Then, when the user stretches out the hands 22 in front of the hand detecting sensor 27 a, the control section (not shown) controls to drive the gas supply device 24 based on the detection signal from the hand detecting sensor 27 a. In this manner, the gas is introduced into the chamber 28 via the air duct 25 and the pressure is uniformalized within the chamber 28. As a result, the gas is blown all over the inserted hands from the gas blowing port 27 at the uniform or constant velocity of wind to start drying the hands 22.

[0131] In this manner, since the user can dry his hands 22 immediately after hand-washing, usability of the hand-washing device A improves. Since the counter 10, a floor or the like is not dirtied or polluted with the drops of water or the like adhered to his hands 22, it is possible to keep the space clean. Further, since the hands 22 can be inserted within the bowl section 103 for drying, there is little possibility that the drops of water or the like blown off from the hands 22 dirty or pollute the counter 10 or the like, and the cleanliness can be further improved. By situating the gas blowing port 27 on the front wall surface of the bowl section 103 near the user, the gas blown from the gas blowing port 27 is blown off in the direction away from the user. Accordingly, there is little possibility that after striking the hands 22, the gas strike the user to rumple or dishevel his hairstyle or the drops of water or the like blown off by the gas splash onto the user. It is therefore possible to obtain a comfortable feeling of use. Further, since the drops of water or the like blown off by the gas can be caught at the extension section 106, there is little possibility that a wall surface W to which the hand-washing device A is secured is dirtied or polluted with scattering of drops of water or the like. Still further, since the blowing motion of gas is automatically made by the hand detecting sensor 27 a, the user is not required to touch the appliance or the like and it is hygienic and good for his health. Since the chamber 28 is also integrally formed with the bowl section 103, it is possible to reduce the number of parts used and reduce the cost as well.

[0132] Furthermore, an operation switch (not shown) can be provided in position to switch ON when the wash-hand basin 1 is cleaned, and the control section (not shown) can prevent the cleaning fluid supply device 2, the hot and cold water supply device 3 and the gas supply device 34 from operating for a certain period of time. In this manner, it is possible to prevent the cleaning fluid or the hot water from scattering to dirty or pollute the counter 10, the wall surface W or the like. It is also possible to prevent the cleaning fluid, the hot water or electricity from wastefully being consumed.

[0133] Installation of the wash-hand basin main body 11 onto the counter 10 can be effected by the under-counter method as per the embodiment shown in FIG. 3. However, it is also possible to adopt the casing 107 formed in the hollow box shape as per the embodiment shown in FIGS. 4 and 5 in place of the cabinet 100.

[0134]FIG. 8 is a perspective view of the external appearance showing a third embodiment of a hand-washing device A according to the present invention and FIG. 9 is a schematic cross-sectional view showing the third embodiment of the hand-washing device A according to the present invention. In these figures, the same reference numerals are used for the same construction as the first and second embodiments and the description for that will be omitted.

[0135] As shown in FIGS. 8 and 9, an opening section 106 b formed on a front wall 106 a of the extension section 106 is provided with a gas blowing port 29. Provided near the gas blowing port 29 is a hand detecting sensor 29 a for detecting the hands 22 inserted into the bowl section 103 to drive the gas supply device 24.

[0136] A chamber 30 is integrally formed with the gas blowing port 29 within a hollow section 106 c of the extension section 106. One end of an air duct 25 is connected to the chamber 30.

[0137] Even in such a construction, the user can dry his hands 22 without shifting his position and therefore, usability of the hand-washing device A improves. Further, since the counter 10 of the wash-hand basin 1, a floor or the like is not dirtied or polluted with the drops of water and the like adhered to the hands 22, clean space can be maintained.

[0138] In this embodiment, it is not always necessary to let the high-pressure gas blow. The hand-washing device A can be designed to let the gas blow at a low speed from the gas blowing port 29 to reduce the possibility that the scattered water such as the drops of water adhered to the hands 22 splash onto the user.

[0139] It is to be noted that the above description only relates to one embodiment of the present invention and it does not mean that the present invention is limited to the above. For example, the hot and cold water mixed cock 20 is provided as the hot and cold water supply device 3 to supply the water ejection port 12 with the hot water. However, only water can be supplied to the water ejection port 12 without provision of the hot and cold water mixed cock 20.

[0140] Further, the chamber 28 is integrally formed with the bowl section 103, but it can be formed using the other member such as synthetic resins. It is also possible to provide a heating means such as a heater in a supply route of gas from the gas supply device 24 to the gas blowing ports 27 and 29. In this case, the gas can be heated by the heating means to let the warm air blow from the gas blowing port 27.

[0141] Next, preferred embodiments of a second group of invention according to the present invention will be explained with reference to the accompanying drawings. FIG. 10 is a perspective view of the external appearance showing the entire structure of a hand-washing device according to the present invention and FIG. 11 is a front view showing the internal space of the lower section of a counter.

[0142] As shown in FIGS. 10 and 11, a hand-washing device B is composed of a counter 59 and a wash-hand basin main body 58 fitted into the counter 59. The wash-hand basin main body consists of a soapy water ejection port 53 and a water ejection port 54 which are provided on an extension section 52 a formed by extending upward a rear section of a water receiving section 52, a soapy water refilling port 56 provided on a side of the water receiving section 52, a gas blowing port 55 provided on a front section of the water receiving section 52, and a drain port 57 provided on a lower section of the water receiving section 52.

[0143] The water receiving section 52 is formed in a substantially oval shape which is wide in a lateral direction. The soapy water refilling port 56 is provided on the left side of the figure. Reference numeral 62 is a soapy water refilling container A polyethylene bottle of 2 liters with the length of 350 mm which is usually used as a plastic bottle for drinking water generally put on the market can be used as the soapy water refilling container 62. It is therefore desirable that the long dimension of the water receiving section 52 in the lateral direction be 350 mm or more. With this construction, since the soapy water refilling container 62 is easily housed in the lateral direction within the water receiving section 52, it is possible to simply refill the soapy water in a comfortable position from the soapy water refilling port 56 within the water receiving section 52. Even though the soapy water spills out of the soapy water refilling port 56, it is possible to easily clean away the spilt soapy water.

[0144] It is also desirable that the soapy water refilling port 56 be situated at a position of about ⅓ depth (desirably about 100 mm from the upper end) from the upper end of the depth of the water receiving section 52 from the upper end to the bottom surface thereof. In such a construction, since an inlet of the soapy water refilling container 62 can be easily situated relative to the soapy water refilling port 56 when the soapy water is refilled, it is possible to easily carry out the refilling operation without spilling the soapy water.

[0145] The wash-hand basin main body 58 is installed at the substantially central section of the counter 59 by a method such as a self-rimming method or a frame method.

[0146] A cabinet section 51 is provided under the counter 59. Housed within the cabinet section 51 are a soapy water supply means 63 for supplying the soapy water ejection port 53 with the soapy water, a water supply section 66 for supplying the water ejection port 54 with water, and a gas supply means 67 for supplying the gas blowing port 55 with high-pressure gas.

[0147] The soapy water supply means 63 is composed of a tank 64 for filling the soapy water, the soapy water refilling port 56 for refilling the soapy water into the tank 64, a supply route 65 for allowing the tank 64 to communicate with the soapy water refilling port 56, and a pump P for supplying the soapy water ejection port 53 with the soapy water within the tank 64 via a soapy water supply route 68.

[0148] The water supply section 66 is provided to communicate and connect with the water ejection port 54 via a water supply pipe 69, while the gas supply means 67 is provided to communicate and connect with the gas blowing port 55 via a gas supply pipe 70.

[0149] Hand detecting means 60 and 61 are provided near the soapy water ejection port 53 and the water ejection port 54 respectively to detect the hands stretched out by the user. A control section (not shown) is provided to control an ejection motion from the soapy water ejection port 53 and an ejection motion from the water ejection port 54 based on the detection signal from the hand detecting means 60 and 61.

[0150] Further, a hand detecting means (not shown) is provided near the gas blowing port 55 to detect the hands stretched out by the user. A control section (not shown) is also provided to control a gas blowing motion from the gas blowing port 55 based on the detection signal from the hand detecting means.

[0151] Operation of the hand-washing device B constructed above will now be explained.

[0152] When making a hand washing motion, the user stretches out his hands near the soapy water ejection port 53. The hand detecting means 60 detects the hands and the detection signal is then inputted to the control section. The pump P is actuated to allow the soapy water ejection port 53 to eject the soapy water via the tank 64 and the soapy water supply route 68. In this manner, the user can now make a motion to remove dirt, bacteria or the like adhered to his hands.

[0153] Next, when the user stretches out his hands near the water ejection port 54, the hands are detected by the hand detecting means 61 and the detection signal is inputted to the control section. The water supply section 66 is then actuated to allow the water ejection port 54 to eject water via the water supply pipe 69. In this manner, the user can now make a motion to wash away the soapy water attached or adhered to the hands.

[0154] After the hand-washing motion, when the user stretches out his wet hands near the gas blowing port 55, the hands are detected by the hand detecting means (not shown) and the detection signal is inputted to the control section. The gas supply means 67 is then actuated to allow the gas blowing port to blow off the high-pressure gas via the gas supply pipe 70. In this manner, water or the like attached or adhered to the hands are blown off to start drying the hands.

[0155] The ejected soapy water, the ejected water, blown water or the like are then discharged from the drain port 57.

[0156] When refilled, the soapy water is refilled from the soapy water refilling port 56 using the soapy water refilling container 62 or the like to be stored in the tank 64 via the supply route 65.

[0157]FIG. 12 is a partially cross-sectional view showing a detachable means between a lid 71 and a soapy water refilling port 56 and FIG. 13 is a cross-sectional view taken along line X-X of FIG. 12.

[0158] As shown in FIGS. 12 and 13, the lid 71 is detachably mounted on the entrance to the soapy water refilling port 56 by a detachable means. The lid 71 is designed to cover the soapy water refilling port 56 except when the soapy water is refilled.

[0159] The detachable means is composed of a concave area 56 a formed on the inner periphery of the soapy water refilling port 56, a convex area 71 a formed on the outer periphery of the lid 71 to be inserted into the concave area 56 a for engagement, a groove area 71 b formed on the inner surface of the soapy water refilling port 56 to allow the convex area 71 a to pass from the concave area 56 a, and a spring 72 inserted between the inner periphery of the soapy water refilling port 56 and the outer periphery of the lid 71 to energize the lid 71 in the direction away from the soapy water refilling port 56 when the lid 71 is mounted on the soapy water refilling port 56. Reference numeral 71 c is a grip section for holding the lid 71.

[0160] When the lid 71 is rotated by holding the grip section 71 c as shown by the arrow of FIG. 13, the convex area 71 a of the lid 71 moves along the concave area 56 a of the soapy water refilling port 56. When the convex area 71 a reaches the position of the groove area 71 b, the engagement of the convex area 71 a with the concave area 56 a is disengaged, and the lid 71 is caused to rise by the energizing force of the spring 72. In this manner, the lid 71 can be easily dismounted from the soapy water refilling port 56.

[0161] Thus, mounting of the lid 71 on or dismounting thereof from the soapy water refilling port 56 can be easily carried out in a simple construction. In addition, it is possible to prevent garbage or the like from entering the soapy water refilling port 56.

[0162] It is also possible to form the convex area on the soapy water refilling port 56 and to form the concave area and the groove area on the lid 71.

[0163]FIG. 14 is a partially cross-sectional view showing another embodiment of a detachable means between the lid 71 and the soapy water refilling port 56 and FIG. 15 is a rear view of the lid 71 as seen from the back.

[0164] As shown in FIGS. 14 and 15, the detachable means is constructed to have the lid 71 provided with an inner joint 71 e for jointing with the inner periphery 56 c of the soapy water refilling port 56 and with an outer joint 71 d for jointing with the outer periphery 56 d of the soapy water refilling port 56. The inner joint 71 e and the outer joint 71 d are partially cut out to provide a cutout section 71 f in which an energizing member 74 with a pressure contact section 74 a energizing toward the inner periphery 56 c of the soapy water refilling port 56 is situated.

[0165] Accordingly, when the lid 71 is dismounted from the soapy water refilling port 56, the energizing member 74 is reduced against the energizing force to loosen the pressure contact section 74 a of the energizing member 74 pressing against the internal periphery 56 c of the soapy water refilling port 56. In this manner, the lid 71 can be dismounted or removed from the soapy water refilling port 56. When the lid 71 is mounted on the soapy water refilling port 56, the energizing member 74 is likewise reduced against the energizing force to allow the lid 71 to be inserted into the soapy water refilling port 56. Once reduction of the energizing member 74 is released, the pressure contact section 74 a of the energizing member 74 is driven to contact the internal periphery 56 c of the soapy water refilling port 56 by its energizing force. In this manner, the lid 71 can be mounted on the soapy water refilling port 56.

[0166] Even in such a construction, the lid 71 can be detachably mounted on the soapy water refilling port 56 using a simple construction without difficulty. It is also possible to prevent the garbage or the like from entering the soapy water refilling port 56.

[0167] The energizing members 74 are first reduced from both sides to allow two pressure contact sections 74 a to forcibly contact the inner periphery 56 c of the soapy water refilling port 56. However, the present invention is not limited to this embodiment. For example, only one side of the energizing members 74 can be reduced to allow one pressure contact section 74 a to forcibly contact the inner periphery 56 c of the soapy water refilling section 56. It is also possible to provide two or more pressure contact sections 74.

[0168]FIG. 16 is a partially cross-sectional view showing a still further embodiment of a detachable means between the lid 71 and the soapy water refilling port 56.

[0169] As shown in FIG. 16, when the lid 71 is made of an elastic body and mounted on the soapy water refilling port 56, the lid 71 is formed to have an arc shape in section so that it projects inside the water receiving section 52. The lid 71 is also provided on the outer periphery thereof with an engaging section 71 g for engaging the soapy water refilling port 56, while the soapy water refilling port 56 is provided on its outer surface with a section 56 e to be engaged by the engaging section 71 g.

[0170] Accordingly, when the lid 71 is dismounted or removed from the soapy water refilling port 56, the central part of the lid 71 is pushed. As a result, the lid 71 is bent backward in the arc shape to disengage the engaging section 71 g from the section 56 e to be engaged. In this manner, the lid 71 can be dismounted or removed from the soapy water refilling port 56.

[0171] Even in such a construction, the lid 71 can be detachably mounted on the soapy water refilling port 56 with a simple construction without difficulty. It is also possible to prevent the garbage or the like from entering the soapy water refilling port 56.

[0172]FIG. 17 is a partially cross-sectional view showing a still further embodiment of a detachable means between the lid 71 and the soapy water refilling port 56.

[0173] As shown in FIG. 17, the lid 71 is respectively provided with magnets 75 and 75 at the symmetrical position of its outer periphery, wherein one magnet 75 is situated inside the lid 71 more inward than the other magnet 75. Metal members 76 and 76 adhered or attracted to the magnets 75 and 75 are also provided on the soapy water refilling port 56.
